A system and method for enabling identification of and engagement with, high-value participants within the venue of a live-event from data collected and saved at events for providing improved customer service, marketing of products and increasing ticket sales to events are disclosed. An on-site wireless captive portal technology is used to authenticate attendees to live-events, and, upon authentication, collect their personal preferences and social profile details in real-time. The information collected at the live event is used to update a historic database at a main server station. The collected information is saved, combined with pre-saved historic data and data-mined to extract values for influence (i.e., number of followers who interact and follow an individual), social value (i.e., blogs and comments generated), and economic value (i.e., spending activity). The current and consolidate data is used to generate information and displays that show the impact of the influence and activities.
